TYPE-WRITING MACHINE.

Specication of Letters `Patent.

Application filed March 29, 1913.

Be it known that l. HEiniEirr H. STEELE, citizen of the llnited States, and resident of Marcellus, in th'e'couiityvof.Onondaga and State of New York, have invented certain new and useful Improvements in YType- Writing Machines, of which the following is a sp'ecitication.

My present invention relates to case shifting mechanism for typewriting machines and its general object is to provide new and 'improved mechanism of the character specified.

More specilically one object of the invention is to provide mechanism that is alitoiiiatieally operative to change case or vary tne relationship between the platen and printing elements so that ditl'erent characters on the latter may be employed.

IAnother object is to provide case shifting devices automatically operative at predetermined points in the travel of the carriage.

vAnother object is to provide case shi ting devices automatically operative by tabulat ing mechanism.

Another object is to provide type bar shifting mechanism operative in the manner and b v the means above specified.

To the above and other ends my invention consists in the fiatifres of construction, combinations of devices and arrangements otl parts hereinafter described and particularly pointed out in the claims.

i In the accompanying drawings, Figure 1 is a fragmentary end view partly in section of a Monarch typewriting machine embodying inc i'orm otl my invention. Fig. Q is a fragmentary sectional View taken on a plane indicated by the dotted line .r in Fig. 1 and looking in the direction ot the arrow at said line. Fig. 3 is a view corresponding to Fig. .2 but showing the parts in different rela tions. some of the parts shown in Fig. 2 being omitted. Figs. 4 and 5 are operating views showing Sonie ot' the parts of Fig. 2 in different relations. Fig. is a fragmeir tary central sectional view taken tore and aft of a No. 11 Remington typcwriting machine embodyingr a moditication of my in ventioii. Fig. i' is a fragmentary vertical sectional view taken on a plane indicated by thi` dotted line a in Fig. (i and looking in the direction of thcy arrow at said line.

Referring first to the construction shown comprises a base 1, posts 2 and a top plate 23 above which are fixed grooved track-ways l which cooperate through aiiti-friction balls with they grooved rear bar of a traveling carriage (i on which is mounted a rotary platen or platen element 7. The carriage is constantly impelled leftward by a motor or spring drinn 8 with which it is connected byA a band or strap Sl. leftward movement being, however, controlled by carriage feeding. devices comprising a feed rack 10 secured to arms` 11 pivoted at 12 on the carriage, said rack normally meshing with a feed pinion 13 which is supported on the forward end of a shaft 14, said shaft bearing in a bracket 15 secured to the top plate. (,)peratively connected with said shaft is a toothed escapement wheel 16 with which cooperate dogs or detents 17 and 18 mounted on a carrier or rocker 19 which is actuated from the printing keys by devices not herein shown but which are preferably of the usual construction found in the Monarch typewriting machine. Cooperative with .the front. face of the platen are printing elements or type bars 20, each type bar being provided at its free end with a type block 21 provided with a lowercase type 22 and an uppercase type 23. Each type bar is pivoted at 24 on a hanger 25 which is secured by a screw 2(3 to the front face of a shiftable element or segincnt 27. The type bars and hangers` arf.` ciicularly arranged at the front face of the segment which is vertically disposed, and the free ends of the type bars are supported norA mally by a curved rest 28 which is mounted on arms 2S) secured to the segment 2T, the construction being such that when thc segment is shifted up and down to change case, as it is called in the art, that is to bring one; of the sets of tvpes 2:2 or 28 into use while carrying the 'ot ier out of use, the type bars will move bodily up and down with the segment 0r suppoit 27 without their relation-I ship with said support being substantialfly varied. A machine of this style in which the type bars are shifted or varied intheir normal positions to effect a change] (if types or change of case is known variously asA a type bar shifting, or segment shifting or type basket shifting inachifne [he actuating devices for each type bar .emprise a lilik 30 which connects the typhar with the upper end of a sub-lever 31 slotted at its lower end iii Figs. 1 to 5, inclusive, the main frame i at 32 to eoperate with a tixcd abutment cr guide 33. The sub-lever is pivoted at 3l on a key lever fulcrumed at its rear on a plate 3G and provided at its upturned forward end with a key cap 37. An actuation of any key lever will, through the described mechanism, cause the connected type bar to swing to the printing point to cooperate with the platen through a ribbon (not shown). Each type bar is provided with .a restorin spring 38. When the type bars are shifted to change case the links 30 swing about their points of connection with the sublevers 31 as centers so that the subdevers and key levers are not a'tfected by case shifting operations.

The segment or type bar lsupport provided at its ends with upright grooved guide ways 39 which cooperate through anti-friction rollers 40 with grooved track-ways formed in the inner faces of upright posts 0r standards 41 which are secured to the baserof the machine. The segment is adapted to be shifted up and down'on the posts or guides by key controlled devices of ordi nary construction comprising arms or links 42 connected at 43 to the lower part of the segment. Each arm 42 is pivotally conA nected at 44 to a crank arm 45 which is curedto a rock shaft .46 and is supported at its ends from the'sdes of the base. Projecting forward from the rock Shaft 4G quite close to each end thereof is a crank arm 47 to which is adjustahly secured by a screw 48 a second crank arm 49 provided at its end with a roller 50 which cooperates with the `under edge of a shift lever 51, said 'ft lever havin` a fixed fulcrrm 5:3 and be provided at its rear end with a restoring;` springr 5S and at its front end with a key o4'. There are two oi these keys one at cach side of the lower bank of keys in the key board of the machine and each operated through the described train of connections to shift the segment upward so that the uppercase types on the type blocks may la) rendered eil'cctiw. Thil-c is also provided at the left end of the upper bank ot' lows a shift lock key which operates'a lever 5G to lock the segment in uppercase position` from which it may be released by an actuation of the lett-hand key 5l, .liar-h ot the keys 54 when actuated independentlj.' operates to shift the segmcu ten'iporarily.

segment when released returning to no. nal position under the impulse kof gravity vihic: is sufficient to overcome the et` ct. of the usual couiiterbalancingr spring 5i, cnc end of which is connected to a pinitwon the rock shaft 4G and the other end of which is auchored fixedly. Stop devices are provided for limiting the up and down shifting movements of the segment, said devices compris` ing lugs or stops 5) and (EO projecting rearA wardly from thesegjment L17 at its ends. (We operative with the stop lugs Btl/and t() are stop arms ('11 and (32 adjustably secured b v said screws 63 to the posts 41. There are two sets of these stop devices one at each end of the segment. Under normal conditions the stops 5t) cooperate with the inner ends of the stops (il as shown in Fig. 2, thus limiting'the downward movement ofthe segment. lVhen the segmnet is shifted upward it is arrested and the extent of its shift movement determined by the engagement of the stops (SO with the inner ends of the stops 02 as shown in'lfig. The case shifting mechanism as thus far described is the regular shi titing mechanism of the Monarch typewriter.

Denominational tabulationl mechanism of the usual construction is provided, said mechanism comprising a` toothed stop bar tilt supported on lugs o5 secured to the carriage and receiving one or more adjustable column stops (t'i (Fig. 2). Coperative with the column stops are denominatie nal stop levers (37 pivotcd at tifa' on a frame t3?) detacnablj; secured to the main frame of the machine. The lower ends of the stop levers (i7 are actuated by Slide bars 70 which in turn are pushed rearward by crank arms 71 secured to rock shafts 7i? on a frame 73 det'aclnibly mounted on the main frame near the front thereof. Said rock shafts are actuated by crank arms or key levers 7st, each provided with a tabulator key 75. which, when operated, acts through the descibed mechanism to project the upper end of the associate .stop lever (37 forward into the path of the olui'nn stops. Each stop lever t3? when operated also releases the carriage from its stcp-by-step feeding devicesthrough releasing mechanism comprising a universal bar or bail 7o, the horizontal body portion whereof is arranged behind the lower arms of the levers (S7. The end portions of said bail ar\ pivoted at 77 and one of them has a forward extension 7S connected by a link 'i'.i to a lever 8() which operates a rack litt er Sl to swing the feed rack lt) up out of mesh ith the feed pinion 13, thus freeingl the carriage for continuance leftward movement under the pull of the spring; drum S. Such movennut or tahulatingv run will continue until the carriageeis arrested b v the cop eration of the projected stop lever (37 with` the proximate column stop 6G.

Referring now particularly to the novel parts of the present construction it has been found desirable in some kinds of typewriting as in way-billing to .write the data, other than the numbers, in capital letters because the size of the capitals renders them easier to read. These capital letters in case shift machines are so placed on the type bars as to require a case shiftingr operation to enable them to be used. Numeral characters, on the other hand. are usually in the lower-case p0- sition on the type bars and are brought into use without the shifting. Consequently when ilo the usual typewriting machine is employed for work ot the character specified, considerahle time is wasted in the case shitting operation` itV beingr necessary. say. to shi't't the type basket. or the platen as the ease may be, to enable the first portion of a line to be written in capitals and then to shift back to lower-case position in order to enable the numerals, usually at the right-hand side of the sheet or the latter portion of the line, to be written in. As a result special machines have been provided having single type bars, the types `being! capitals. usually gothic. and the small letters or lower-case types being eliminated except that the numeral types are retained; but ofcourse these special machines are not adapted for ordinary typewriting. l

The chief object of the present embodiment of my invention is to provide a case shifting machine of regular construction with means for enabling it to be used for ordinary typewriting and also for writing` way-bills or other similar typewriting in r' the way specitied above as desirable. that is,

in writing the parts of the lines in uppercase types or capitals and other parts of the same line in lowercase types, usually numerals. In carrying out this object in the present instance, I provide devices for automatically shifting the type basket up and down; thesev devices being actuated by a special stop which m-ay be adjusted as desired on the column stop 'bar 64, said stop operating, when f the carriageais moving in one direction, to

shift the type basket to the uppercase position at a predetermined point in the travel of the carriage or in the printing line, while during the travel of the carriage in the opposite direction the reverse case-shifting;l operation .takes place and the type basket shifts back to normal or lowercase position. This automatic case -shifting mechanism does'not interfere with the operation in the ordinary way of the regular key operated case shifting mechanism heretofore described; and furthermore" the key operated devices may be actuated at an time without interfering with theautomatic devices. Said automatic devices, in the` present instance, comprise a rock shaft 82 arranged fore and aft of the machine at the righthand side. Said rock shaft bears at its forward end in a hole in the right-hand post 4-1, the hole being formed' in the rear face of the post between the stops 61 and. 62. The rear end of said shaft bear'e in a bracket or arm 83 secured by screws 84 to the right-hand rear post 2, as best appears in Fig. 2, which is arear view. Fixed to the rock shaft 82 near its forward end is a crank arm'85, said crank arm extending horizontally inward and underlying a stud or pin 86 which is fixed in the segment 27 and projets rearwardly therefrom in position to be engaged by the arm 85. The rear end portion of the shaft 82 has fixed to it a crank arm ST, said crank arm extending inward and having` pivotally connected to it at 88 the lower end ot' an ul'irigl'lt link 80, the npper. end whereof is pivotally connected at 00 the hert lioriyzontally disposed arm 0f a bell crank 91 pivoted at 92 to an angular bracket 03 screwed at 94 to the underside et' the plate. The lcngcr or` upright arm of the bell crank 91 has pivotally connected to it at 95 the right-hand end of a link 00 which extends leitward under the top plate and is pi\.ttall connected at 0T with the lower arm of a lever member designated as a whole as 08. Said lever member extends downward through an opening fl" in the top plate and is fulcrumed on a hezuled and shouldered screw 99 which is secured to the rear tace of the bracket l5. 'lhe upper arm of the member 98 is enlarged, as indicated at 100, the enlargement being formed with an arcuate slot or opening 101 which tits over the barrel portion l5n of the bracket 15. The outer left-hand face ot the portion 100 is formed on a curve having.;v as a center the avis ot rotation of the. lever 0S, the curved face 1.02 terminatingr at its lower end in a stop face 103 and at itsl upper end in a lug or engaging portion or device. 104. This lug is adapted for cooperation with a special column stop 105 which differs from the ordinary column stop (56 in that its forward side extends downward as indicated at 105a below the stop bar (i4- and into position to cooperate wit-h the lug 104 during movements of the carriage. In other respects the stop 105 is like the ordinarystop 60 and may be A adjusted as desired along the stop bar.

livoted on the shouldered screw 99 between the lie-id thereci and the mci'nher 98 is a. trip mend/er 100 terminatingI in an. upwardlv extending' tooth or engaging portion ltf and having a cut out 108 adapted to engage at 'times with the barrel portion 152: Thi,-` rip is adapted to act on and is connected bv a draw spring 105) with a pivcted latch 110, one endof the spring bein I hooked over a piu lll enA the trip and 'the other end rer aI pin 11:2 ou the latch. The latch 1.10 is ot sufficient width al. its upper or free end to cooperate both with the trip 106 and with the lever member' 98. 'Said latch isl arranged at the left of said lever member and is pivoted at its lower end on a headed and shouldered screw 113 which is capocried on' an angular bracket 114. said Ybracket being screwed at 115 to the top lplate.

l -The tpring 109 tende constantly to swing the trip 100 leftward about its pivot and also te draw or swing); the latch 110 downward around its pivot toward the' right. Referring-to Fig. t2 it will be obi served that the swinging mmemcut of the trip' 100 is controlled and limited in oue di'- rection., by a stoppin 116 projecting rear- During,r this movementl of the member 98 the pin 116 will engage with the trip 1013 and w'll torce said trip back with it to the position shown in Fig'. 5. The trip is .shaped to provide a cam surface 1011 which will act on the latch 110 during the movement ot the tri p from the Fig. 11- to the Fie'. :'i position to foree\or cam said latch uinvard on to the rounded'upper ,tace of the trip which connects the cam face 101ia with the tooth 107.

As a result of the described operationsit will be understood that when the carriage is ne.\'t arrested and printinpT ope ations are begun. said printing operations will take place from the lowercase types since the type support or segmert 27 has been restored to the lowercase position. Also the devices comprising the member 98. trip 10S and latch .110 have been restored to the positio-n in Fig. 2, Fig. 5 correspomlingr. in so far as it relates to these parts, ivithilig. y

lt will also be understood that during further movements of the' carriage from right to left the parts will remain in the described positions and the printing.: will be from the lowercase types; and that when the carriage is next restored from left to right to begin a new line the cycle of operations hereinbe` fore described will be repeated. Thus it will be seen that a relative shifting movement between the type elements or type bars and the platen element or platen takes place automatically at predetermined points during,r to and fro movements of the traveling carriage and that this automatic operation is effected by a train of devices which are actuated by part ot' the tabulating mechanism.

- The extent of the shifting movement will be apparent from a comparison of the full and dotted line positions of the upper edge of the segment in Figs. 2 and 3.

lVhile the case shifting operation or relative shift or movement between the printing and type bar elements necessary to etteet a change of case takes place in the construction heretofore described through a shittingr movenient of the type har elements or printing instrumentalities7 the invention equally applicable to a construction wherein such relative movement is effected through a shitting movement of the platen element instead of the type bar elements. Such a construction in which the platen element is shifted is exemplified in Figs. and 7 which illustrate ano-ther .t'orm of my invention applied to a No. 11 Remington typcwritinyj machine. Said Remington machine has a main trame which includes a hase 117. posts 118 and a top plate 1151 above which are fixed grooved track-ways 12() that coperate through antifriction balls 121 with the grooved front and rear hars 122 and 12:1 ot' a rectangular truck which further comprises connectingr end bars 12-1. `Shittably connected with said truck by arms or links 125 provided with a key 145.

is a platen frame or carrier which comprises end bars 1:26, a connecting cross har 127 and a cross rod 128. y Supported rotatably on .said platen frame is a platen or platen elemont 129. 'lho platen carriage comprising the truck and the platen trame is urged leftward by a carriage motor or spring drum 12%() which is connected by a strap 131 with the carriage.

'feed rack 32 mounted on armslpivoted to the truck meshes normally with a pinion 3:1 which is secured to a shaft 133a that bears in a stationary bracket 134, Said shaft being connected with escapement devices ot the ordina y construction not disclosed hcrein. The platen and platen frame may he shifted together at will at any point in the. travel of the carriage. To this end a roller 135 that is mounted on the cross bar -T runs en a shift. rail 136 which is comprised in a shift trarne that further includes rnd bars 1.37 and a cross bar 138 from the .ends whereotl depend arms or bars 131) hav-` ,ing their lower cnds pivotally connected at. 1-1-0 with levers 1-11 tulcrumed on a rod or shaft 112 supported in the sides ot the base. l'The t'orward arms of said levers 141 are connected by a, bail or cross piece 143 which is operative Jfrom shi tt key levers A'tV each An operation of either of the keys 145 el-zvates the shift trame comprising' th-e rail 131'. raising the platen frame and carriage to uppercase position without Iattectingr the carriage truck. counterbalancing spring 14,6 which assists the shitting movement is 'connected to a pin 14-7 on the bail 113. the rear end of said spring being anchored to a stationary Ipin 148, The type 'hars 14.9 are cach provided with a lowercase type 150 and an uppercase type 151 and normally rest at their free ends on a support 152. Each type bar is pivoted in a' hanger 153 which is secured to the, front tace o1l a stationary support or segment. 151. The type bar actuating devices for cach type bar con prise a link 155. a lever 15G and a second link 157. The link 157 is connected with a key lever 15S 'tulcrunied at 151) and provided with a key 1110. Each key lever is also provided with a restoringvspring 1131 and operates through the described connections to actuate the associate type bar` causing one or another of the types 150 and 151 thereon to cooperate with the front face of the platen through a ribbon (not shown), the coperatine4 type depending on theshitt position of the platen. The machinelis provided with tabulatine mechanism ot the usual constructifn comprisiiur1 a toothed colnnm stop bar 1112 mounted on arms 1133 ward from the carriage truck` said stop bar adjustably supportimer one or more column extendingr rear-l ed to coperate with the column stops are a rearwardly off-set lug or tooth 193.

denominational lstop levers 165 pivotally supported at 166 on a stat-ibnary bracket or frame`167, said levers being connected at their lower ends with push rods 168 each of which is provided with a key 169 and a restoring spring 170. Each push rod 168 is provided with a collar 171 which is adapted to actuate carriage releasing devices comprising a pivoted bail 172 connected by links 173 with a crank arm 174 fixed to a rock shaft 175 to whichis also fixed an angular arm 176 that is connected through a link 177 with a releasing'v lever 178 that at its forward end underlies the rack 132 and is adapted to lift the saire out of mesh with the pinion 133 when one of the tabu-later keys 169 is operated. It will=be `understood that the operation of such key projects the upper end. of the associate stop lever 165 into the path of the column stops 164 on the carriage and also releases the carriage from its escapement devices so that said carriage will move freely leftwardiunder the influence of the spring drum until arrested by the engagement of one of the column stops with the projected denominational stop.

The' automatic platen shifting devices comprisea rock shaft 179 that bears at its forward end in a bracket 180 secured by a screw 181 to th-e top plate, the rear end portion of said rock 4shaft bearing in a bracket 182 that is screwed at 183 to the top plate. Forward of the bracket 180a crank arm 184 is secured to the rock shaft 179, said crank arm having a hub portion 185 that is fixed to the shaft, and terminating at its free end in a forwardly bent portion 186 that underlies the shift rail 136 and is curved on its upper face so vas to coperate smoothly therewith. Fixed to the rear end portion of the rock shaft 179 back of the bracket 182 is a crank arm 187 having a hub 188 which fits over and is fast on the rock shaft. The free end of said crank arm 187 is connected by a vertically disposed link 189 which extends through an',

o )onine 1.19n in the to plate with a lever' u'ember 190 fulcrumed on a. shouldered;

screw 191 secured to the front portion of the bracket 134. The member 190 is cnt out as indicated at 192 to fit overthe barrel'portion of said bracket and is provided with A trip 19t having a tooth 195 is pivoted on i the screw 191 in front of the member 190.

.\ latch 196 pivoted at 197 to a fixed bracket 198 is connected by a draw spi-ing 199 with the trip. The lug 193 and the tooth 195 are adapted to cooperateivith a special column stop 200 which rdilers from the ordinary rolumn stop in that it is provided with a downward extension 209. the path whereof is obstructed at times by the lug 193 and the tooth 195,

The platen is shown lin lowercase position 189, crank arm `187, rock shaft 179 and l crank arm 184, 186 to the shift rail 136.

'which Vwill be elevated, lifting the platen frame and platen `to uppercase position, the uppercase position of said platen being indicated by thedotted line in Fig. 6.' The platen willlbe maintained locked in uppercase position by the latch 196 which will drop in behind the member 190 when it has been turned to eifect the shift, said latch cooperating With the corner of said member and the two interlocking with each other to hold the platen locked in luppercase position until the advance of the carriage in printing direction brings thelextension 200aL into engagement with the tooth 195 of the trip 19-1. Said trip, as will be understood, has been moved so that the tooth 195 is in the path of the extension 200a at this time. As a result of the engagement of said stop portion with said tooth the trip will operate on. the latch 196 tov force it upward so thatjit will release the member 190, thus allowing the platen to return to normal or lowercase position. The movement of the platen causes the member 190 and the trip 194 to. be restored to .normal position and the latch will thereby be forced to engage with the trip 194 back ofthe tooth 195 as .in Fig. 7. The operation of the parts, it will be understood, is similar to those ofthe corresponding parts in the lirst described construction.

The principle of operation the same in both constructions and both. constructions -efi`ect an automatic case shifting operation,

the relative movement between the platen and printing elements in the second case bein caused by a movement of the platen whereas in the first case it is caused by amovementy of the type bars. It will be observedlthat the automatic shifting devices do not interfere with the operation of the usual key controlled shifting devices. In the first described construction under operation of the key controlled devices the pin or stud 86 moves up away from the arm 85 and back into contiguity therewith without affecting the automatic devices 'connected to said arm. ln the second described construction when the key operated shift devices are actuated the shift rail 136 moves upward away from and back toward the bent portion or extension 186 without affecting said extension or the connected parts. Further it will be noted that the work of shifting the shiftable element upward in opposition to gravity is performed, in both constructi ons, by utilizing the power applied by the operator in returning the carriage, leaving to the carriage motor or springtr merely the comparatively light work of operating the trip to release said element so that it may be re stored largely through gravity. In both constructions, movement of the traveling element, carriage cr platen is effective to cause operation of the ease shifting mechanism. ln both constructions also the movelnent of the operative traveling member is caused or effected in one direction by the carriage spring drum, and in the opposite direction by the power of the hand employed to retract the carriage.

Various changes other than those described may be made withoutaleparting from my invention. i
